[0003] In the preparation of crude TZV, after the ring-closure reaction is completed, the pH of the reaction liquid needs to be adjusted to about 6.0 with acetic acid and monitored by a pH meter installed on the reactor. However, when the liquid is transferred from the reactor to the equipment of the next process, the electrode of the pH meter will be exposed to the air, which will affect the electrode of the pH meter, thereby affecting the accuracy of the pH meter's detection data and the service life of the pH meter.

[0004] Therefore, an online pH meter electrode protection device for TZV preparation is proposed. Utility Model Content

[0005] The utility model aims to provide an electrode protection device for an online pH meter in TZV preparation.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] Preferably, the top end of the sealing cover is fixedly connected to a display, the bottom end of the display is fixedly connected to a wire, and the display is electrically connected to the pH meter body through the wire.

[0009] Preferably, the top end of the sealing cover is fixedly connected to a motor, the output end of the motor is fixedly connected to a transmission shaft, the bottom end of the transmission shaft extends to the bottom end of the reactor, and the bottom end of the transmission shaft is fixedly connected to a stirring blade.

[0010] Preferably, limiting grooves are provided on both sides of the sliding plate, and limiting rods adapted to the limiting grooves are fixedly installed in the protective shell.

[0011] Preferably, a toggle assembly is provided on the protective shell, and the toggle assembly includes open grooves symmetrically opened on both sides of the protective shell, and bases are fixedly installed at both ends of the sliding disk, and the bases extend out of the open grooves. A connecting rod is rotatably installed on the base, and the bottom end of the connecting rod is fixedly connected to the airbag.

[0012] Preferably, the buoyancy of the air bag in the solution is greater than the gravity of the pH meter body and the corresponding connecting parts.

[0013] Preferably, rotating frames are provided on both sides of the protective shell, and the middle position of the connecting rod is rotatably mounted on the rotating frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. By setting up a protection component, the sliding disk can slide on the outside of the limit rod through the limit groove. At this time, the pH meter body at the bottom of the sliding disk can slide in the protective shell. When the spring pushes the sliding disk to slide upward, the pH meter body can move upward. The pH meter body can be retracted into the protective shell along the through hole. The protective shell can protect the electrodes of the pH meter body, prevent the electrodes of the pH meter body from being exposed to the air, ensure the accuracy of the detection data of the pH meter body, and ensure the service life of the pH meter body.

[0016] 2. By setting up a toggle assembly, when the reactor is filled with reaction liquid, the airbag can float upward with the reaction liquid, and the airbag can toggle the connecting rod to rotate on the rotating frame. At this time, the other end of the connecting rod flips downward, and the sliding disk can slide downward along the limit rod. At this time, the pH meter body can slide downward along the through hole, so that the pH meter body can be extended into the reaction liquid, which is convenient for monitoring the pH value of the reaction liquid. When the reaction of the reaction liquid is completed, the reaction liquid is discharged from the discharge pipe. At this time, the liquid level of the reaction liquid drops, and the airbag loses its support to drive the connecting rod to flip downward. With the help of the spring, the pH meter body can be retracted into the protective shell, which can reduce the difficulty of the spring rebound and is beneficial to the protection of the pH meter body.

The protection component comprises a protection shell 9 fixedly installed at the bottom end of the sealing cover 3, a sliding disk 12 is slidably installed in the protective shell 9, and the center of the sliding disk 12 is fixedly connected to the pH meter body 17, a spring 18 is provided between the bottom end of the sliding disk 12 and the bottom wall of the protective shell 9, and the spring 18 is sleeved on the outer side 17 of the pH meter body, and a through hole 16 adapted to the pH meter body 17 is opened at the bottom end of the protective shell 9.

[0026] See also Figure 2 The top end of the sealing cover 3 is fixedly connected to the display 4, and the bottom end of the display 4 is fixedly connected to the wire 11. The display 4 is electrically connected to the pH meter body 17 through the wire 11.

[0027] See also Figure 2 The top of the sealing cover 3 is fixedly connected to a motor 5, the output end of the motor 5 is fixedly connected to a transmission shaft 7, the bottom end of the transmission shaft 7 extends to the bottom end of the reactor 1, and the bottom end of the transmission shaft 7 is fixedly connected to a stirring blade 8.

[0028] See also Figure 4 , limiting grooves 21 are opened on both sides of the sliding disk 12, and a limiting rod 20 adapted to the limiting grooves 21 is fixedly installed in the protective shell 9.

[0029] In this embodiment, when in use, the sliding disk 12 can slide on the outside of the limiting rod 20 through the limiting groove 21. At this time, the pH meter body 17 at the bottom end of the sliding disk 12 can slide in the protective shell 9. When the spring 18 pushes the sliding disk 12 to slide upward, the pH meter body 17 can move upward. The pH meter body 17 can be retracted into the protective shell 9 along the through hole 16. The protective shell 9 can protect the electrodes of the pH meter body 17, prevent the electrodes of the pH meter body 17 from being exposed to the air, ensure the accuracy of the detection data of the pH meter body 17, and ensure the service life of the pH meter body 17.

[0030] Example 2:

[0031] See also Figures 1 to 3 A TZV preparation online pH meter electrode protection device also includes: a toggle assembly arranged on a protective shell 9, the toggle assembly includes open grooves 19 symmetrically opened on both sides of the protective shell 9, and bases 13 are fixedly installed at both ends of a sliding disk 12. The base 13 extends outside the open groove 19, and a connecting rod 14 is rotatably installed on the base 13. The bottom end of the connecting rod 14 is fixedly connected to the airbag 10.

[0032] See also Figure 3 The buoyancy of the airbag 10 in the solution is greater than the gravity of the pH meter body 17 and the corresponding connecting parts.

[0033] See also Figure 3 A rotating frame 15 is provided on both sides of the protective shell 9, and the middle position of the connecting rod 14 is rotatably mounted on the rotating frame 15.

[0034] In this embodiment, during use, when the reactor 1 is filled with reaction liquid, the airbag 10 can float upward with the reaction liquid. At this time, the airbag 10 can drive the connecting rod 14 to rotate on the rotating frame 15. At this time, the other end of the connecting rod 14 flips downward. At this time, the sliding disk 12 can slide downward along the limit rod 20. At this time, the pH meter body 17 can slide downward along the through hole 16, so that the pH meter body 17 can be extended into the reaction liquid, which is convenient for monitoring the pH value of the reaction liquid. When the reaction of the reaction liquid is completed, the reaction liquid is discharged from the discharge pipe 2. At this time, the liquid level of the reaction liquid drops, and the airbag 10 loses support and drives the connecting rod 14 to flip downward. In conjunction with the spring 18, the pH meter body 17 can be retracted into the protective shell 9, which can reduce the difficulty of the spring 18 rebounding, which is beneficial to the protection of the pH meter body 17.

At this time, the motor 5 can drive the transmission shaft 7 to rotate, and the stirring blade 8 at the bottom end of the transmission shaft 7 can stir the reaction liquid, which can accelerate the mixing of the reaction liquid. During the reaction process, when the reactor 1 is full of reaction liquid, the airbag 10 can float upward with the reaction liquid. At this time, the airbag 10 can drive the connecting rod 14 to rotate on the rotating frame 15. At this time, the other end of the connecting rod 14 is flipped downward. At this time, the sliding disk 12 can slide downward along the limit rod 20. At this time, the pH meter body 17 can slide downward along the through hole 16, so that the pH meter body 17 can be inserted into the reaction liquid, which is convenient for monitoring the pH value of the reaction liquid. The display 4 on the top of the sealing cover 3 can quickly understand the pH value of the reaction liquid. PH value, and when the reaction of the reaction liquid is completed, the reaction liquid is discharged from the discharge pipe 2, at this time the liquid level of the reaction liquid drops, the airbag 10 loses support and drives the connecting rod 14 to flip downward, and cooperates with the spring 18 to retract the pH meter body 17 into the protective shell 9, which can reduce the difficulty of the spring 18 rebounding, which is beneficial to the protection of the pH meter body 17. When the spring 18 pushes the sliding disk 12 to slide upward, the pH meter body 17 can move upward at this time, and the pH meter body 17 can be retracted into the protective shell 9 along the through hole 16. The protective shell 9 can protect the electrodes of the pH meter body 17, and can prevent the electrodes of the pH meter body 17 from being exposed to the air, thereby ensuring the accuracy of the detection data of the pH meter body 17 and ensuring the service life of the pH meter body 17.
